Influence of Time Delay on Bifurcation in Fractional Order BAM Neural Networks With Four Delays

open access: yesIEEE Access, 2019
Over the past several decades, numerous scholars have studied the stability and Hopf bifurcation problem of integer-order delayed neural networks. However, the fruits about the stability and Hopf bifurcation for fractional-order delayed neural networks ...

Hopf bifurcation in delayed nutrient-microorganism model with network structure

open access: yesJournal of Biological Dynamics, 2022
In this paper, we introduce and deal with the delayed nutrient-microorganism model with a random network structure. By employing time delay τ as the main critical value of the Hopf bifurcation, we investigate the direction of the Hopf bifurcation of such

The Hopf bifurcation with bounded noise [PDF]

open access: yesDiscrete & Continuous Dynamical Systems - A, 2012
We study Hopf-Andronov bifurcations in a class of random differential equations (RDEs) with bounded noise. We observe that when an ordinary differential equation that undergoes a Hopf bifurcation is subjected to bounded noise then the bifurcation that occurs involves a discontinuous change in the Minimal Forward Invariant set.

Controlling hopf bifurcations: Discrete-time systems

open access: yesDiscrete Dynamics in Nature and Society, 2000
Bifurcation control has attracted increasing attention in recent years. A simple and unified state-feedback methodology is developed in this paper for Hopf bifurcation control for discrete-time systems. The control task can be either shifting an existing

Hopf Bifurcation Control in a Delayed Predator-Prey System with Prey Infection and Modified Leslie-Gower Scheme

open access: yesAbstract and Applied Analysis, 2013
Hopf bifurcation of a delayed predator-prey system with prey infection and the modified Leslie-Gower scheme is investigated. The conditions for the stability and existence of Hopf bifurcation of the system are obtained.

Hopf Bifurcation and Chaos in Tabu Learning Neuron Models [PDF]

open access: yes, 2004
In this paper, we consider the nonlinear dynamical behaviors of some tabu leaning neuron models. We first consider a tabu learning single neuron model. By choosing the memory decay rate as a bifurcation parameter, we prove that Hopf bifurcation occurs in

Bifurcation Analysis and Sliding Mode Control of Chaotic Vibrations in an Autonomous System

open access: yesJournal of Applied Mathematics, 2014
We study the bifurcations and sliding mode control of chaotic vibrations in an autonomous system. More precisely, a Hopf bifurcation controller is designed so as to control the unstable subcritical Hopf bifurcation to the stable supercritical Hopf ...

Hopf bifurcation analysis of Sel’kov model with time delay

open access: yesXi'an Gongcheng Daxue xuebao, 2023
The Sel’kov model with time-delay diffusion under homogeneous Neumann boundary conditions is considered. Firstly, the local asymptotically stability of the positive equilibrium point of the model is obtained by using spectral theory.
